# Glossary

> The terms used across PRODUCT_NAME, in plain language.

## Stock and costing

**On hand** — how many units the system believes are at a store right now.

**Stock value** — quantity times unit cost. Based on what you paid, not what you
sell it for.

**WAC (weighted average cost)** — the blended cost of everything you currently
hold of a product. Buy the same item at two prices and the WAC lands between
them, weighted by quantity.

**FIFO layer** — a batch of stock at the price you paid for it. Selling consumes
the oldest layer first, so cost of goods reflects what that stock actually cost.

**COGS at sale** — what an item cost you at the moment it sold, captured on the
sales line so history does not change when prices do.

**Reorder point** — the quantity at which a product appears in
[Stock Alerts](https://sims-bae272dd.mintlify.site/stock/alerts.md). **Reorder quantity** is how much to buy.

**Pack size / units per case** — how many sellable units are in a case. Missing
this is the most common cause of wrong stock.

**Movement** — one entry in the [stock ledger](https://sims-bae272dd.mintlify.site/stock/ledger.md). Movements are
never edited; corrections are new movements.

## Buying and receiving

**Purchase invoice** — what a supplier says they sent you.

**Receiving / check-in** — counting what actually arrived. This is what moves
stock.

**Short / over** — a counted quantity below or above the invoiced one. Either
opens a discrepancy.

**Supplier return / credit memo** — goods going back, entered as positive
numbers; confirming removes stock and credits the supplier.

**Price recommendation** — a suggested new selling price after a cost change,
waiting for approval.

## Scanning

**OCR** — reading a photographed document. **Confidence** is how sure the system
is, shown green, yellow or red with the reason.

**UPC** — the barcode. A **case UPC** is the barcode on the outer box.

## Fuel

**Gross gallons** — the volume actually in the tank. **Net gallons** — the same
fuel corrected to 60°F.

**BOL (bill of lading)** — the delivery manifest, stated in net gallons.

**ATG (automatic tank gauge)** — the in-tank sensor, and the daily report it
produces.

**Book inventory** — what the tank *should* hold: opening plus deliveries minus
sales.

**Variance** — book against actual. **Thermal** is the part explained by
temperature; **unexplained variance** is what is left, and the number that
matters.

**EPA log** — the compliance record: variance within 1% of throughput plus 130
gallons.

## Lottery

**Pack** — a book of scratch-off tickets. **Bin** — the dispenser slot it sits
in.

**Activate** — put a pack into a bin. **Settle** — close it out and free the
bin.

**Shift audit** — reading the current ticket number in each bin and comparing
against POS.

**Commission** — what you actually earn. Ticket sales are the state's money.

**Terminal report** — the state's daily figures. **Settlement invoice** — the
state's periodic bill, which supersedes the daily reports it covers.

## Tobacco

**Scan data** — the weekly sales file manufacturers require to pay a rebate.

**UPC mapping** — the link from your product to a manufacturer's brand family.

**Buydown** — a discount at the register funded by the manufacturer, and
therefore money owed back to you.

**Receivable** — buydown money accrued but not yet paid.

## Accounts

**Business** (or workspace) — your company. **Store** — one site, with a store
code.

**Member / Admin / Owner** — workspace roles. **Store role** — the permission
bundle a Member has at a store.

**Agent API key** — the credential a store's Inventory Agent uses.
